Alpha: Alpha testing is an early stage of testing of a game. It’s usually done after a game just finishes being developed. It’s very common for games to be unstable in this stage, as the purpose of alpha testing is to iron out the “obvious” bugs and glitches. Closed: This stage of testing usually comes right after all the problems discovered in Alpha testing are fixed. Open Beta: means the server is released and available to the public. Anyone can register and download the game. In 95%+ of cases, there aren’t "characters wipe" Am i wrong? So now it's me who ask to you do you even understand what closed and open beta means?
